The excess continuum that magnetospheric accretion adds to a CTTSs optical spectrum has been investigated since [1]} first introduced the concept of veiling. With high resolution spectroscopy, it is possible to observe the photospheric absorption lines of the star and this excess due to accretion that effectively veils the spectrum. In [2]}, a quantitative method was developed to measure the amount of veiling present in a given CTTS. By comparing the spectrum of the accreting CTTS, with a spectrum that represents only the photosphere (no accretion present), the following equation is produced:
\(O(\lambda _i) = A\,[S(\lambda _i) + V(\lambda _i)],\)
